Bug Description

This bug is similar to this one:

I file this as a separate one as suggested by @Kai-Heng Feng.

1.I am currently using Ubuntu 16.04.3, but I reproduced this bug on Linux Mint 18.3 (based on 16.04 as well) and on Ubuntu-Mate 17.10. This is a fresh install, not a dist-upgrade.
My laptop is Lenovo Ideapad 320 A6 (very similar laptop configuration to Ideapad 320 ARB).CPU: AMD A6-9220, GPU: RADEON R4

2. Affected Kernel version: 4.13.0-17
Elan Touchpad driver is not working correctly (?)

3. I expected Touchpad to work normally, after installation.

4. Touchpad works for up to 60 seconds and than stops completely. My syslog is spamed with
"elan_i2c i2c-ELAN060B:00: invalid report id data (ff)".
I can make touchpad stop working in about 10 seconds if I move mouse a lot. In attached syslog, You can see 938 error messages in span of 10 seconds. The more I move/click, the faster it freezes.

In this version of kernel xinput is detecting hardware. In earlier versions (kernels 4.4*, 4.10*) there was no touchpad detected.

teo@widelec:~$ xinput
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ PixArt USB Optical Mouse id=9 [slave pointer (2)]
⎜ ↳ Elan Touchpad id=12 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
    ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
    ↳ Power Button id=6 [slave keyboard (3)]
    ↳ Video Bus id=7 [slave keyboard (3)]
    ↳ Power Button id=8 [slave keyboard (3)]
    ↳ EasyCamera: EasyCamera id=10 [slave keyboard (3)]
    ↳ Ideapad extra buttons id=11 [slave keyboard (3)]
    ↳ AT Translated Set 2 keyboard id=13 [slave keyboard (3)]

What I tried:
1. Kernel upgrades
2. Adding different set of options into grub configuration (i8042.reset, nopnp, nomux)
3. Switching on and off elan_i2c module.
4. Changing xserver-xorg-input-libinput to xserver-xorg-input-synaptics and removing xserver-xorg-input-evdev
